One has nothing to do with the other.
You can have sex with out love and love without sex.
Sex is a biological function, a hormonal need and can be nothing more than that. Love, in my opinion, is also biological, and can be strengthened through sex, but can also be strengthened through a myriad of other things. Often, we confuse infatuation with love. Infatuation never lasts. Infatuation is fleeting, but through closeness, which can include sex, it can grow into love.
SunnyMike, I like you more and more every time I see your posts. You "get it". Alas, two separate continents. Oh well.
Dating or relationship does not have to be about love, or sex. Consenting adults can make it about whatever they agree on. If their goals don't align, that's a recipe for disappointment.
